Architecture Overview

IoTBackend has four main parts:

• Device firmware running on your board
• MQTT broker for secure messaging
• Backend services for device management and OTA
• Web dashboard for users

User-level data flow

1. Device connects to MQTT over TLS.
2. Device sends telemetry and subscribes to a command topic.
3. Dashboard shows status, runtime details, and activity.
4. User sends commands or assigns OTA firmware from Dashboard.
5. Device applies updates and reports back through telemetry/events.

Scope boundary

• You build firmware locally.
• IoTBackend manages remote connectivity, control, and OTA.
